Decisions about obesity prevention are being made daily in communities, states, and countries worldwide. The Bridging the Evidence Gap report explains that timely and credible evidence is needed to help decision makers decide what to do and understand how to do it, distinguish actions that are likely to be effective from those that are not, justify particular actions in high-risk populations, quantify likely effects, estimate costs and cost-effectiveness, set priorities regarding specific outcomes, determine who benefits, and anticipate potential problems. The report sponsors — Kaiser Permanente, The Robert Wood Johnson Foundation, and the Centers for Disease Control and Prevention — were motivated by their perception that effective approaches to obesity prevention were proving difficult to identify, creating a risk that ongoing efforts to address the problem would be ill-conceived or haphazard.
Below we describe the evidence framework that resulted from the study committee’s consensus process and provide some examples of how it can be applied to evaluate existing evidence and inform the generation of new evidence. The full Bridging the Evidence Gap report and related summaries, as well as the presentations from 2 workshops convened by the committee, are available from IOM at www.iom.edu/Reports/2010/Bridging-the-Evidence-Gap-in-Obesity-Prevention-A-Framework-to-Inform-Decision-Making.aspx.
